Abstract: The present disclosure presents hydrogel compositions for use in the treatment of an ocular disorder (e.g., a retinal disease) and methods of treating an ocular disorder in a subject in need thereof with the hydrogel compositions. The hydrogel compositions can include hydroxyphenylpropionic acid (gelatin-HPA), hyaluronic acid-tyramine (HA-Tyr), a catalyzer (e.g., horseradish peroxidase (HRP)), a cell, a crosslinker (e.g., hydrogen peroxide), or any combination thereof. The methods include administering a therapeutically effective amount of a composition into an eye of the subject, wherein the composition includes any of the hydrogel compositions of the disclosure.
